ELUSH MPPT Solar Charge Controller 100A — 12/24/36/48V with LCD Display, Dual USB, 100V Input

ELUSH 100A MPPT Solar Charge Controller is a high-capacity, multi-voltage regulator that optimizes PV array output for 12/24/36/48V systems while offering an LCD display, dual USB ports, and broad battery compatibility.

This intelligent regulator combines MPPT tracking with PWM-assisted charging to deliver efficient power management for medium to large off-grid solar arrays. With automatic system-voltage recognition, a multi-function backlit LCD, and protections for over-voltage, reverse connection, and overheating, the unit is built to be a central component in RVs, cabins, backup power systems, and small commercial installations.

How does this controller improve solar panel output and charging efficiency?

The ELUSH 100A uses an advanced MPPT algorithm to find and maintain the array's maximum power point under varying light and temperature conditions, improving energy harvest versus fixed-voltage controllers. It claims tracking efficiency of no less than 99.5% and combines MPPT logic with PWM features for consistent performance across battery types.

• High-accuracy MPPT algorithm for faster maximum power tracking
• Automatic recognition of 12V/24V/36V/48V systems
• Dual USB 5V ports for charging accessories while managing battery charging
• Hybrid MPPT/PWM approach to balance efficiency and cost

What protections and status feedback does the controller provide?

Built-in safeguards prevent common system faults: over-voltage, over-current, deep discharge, overheating, and reverse connections are monitored and handled to protect panels and batteries. The backlit LCD shows real-time parameters so you can confirm operation at a glance.

• Visual display of battery voltage, PV charging current, and temperature
• Alerts and automatic responses for over-charge, power failure, and reverse polarity
• Configurable delay and timing settings to customize behavior
• Seven operating modes including light-control and manual timing

Which battery chemistries and system setups are compatible?

The controller supports sealed lead-acid, GEL, flooded (wet) batteries and LiFePO4 chemistries with selectable charge profiles. It is suitable for single-bank systems up to 100A output and accepts PV inputs up to 100V, making it flexible for a wide range of off-grid and mobile installations.

• Selectable battery charging profiles: Seal, GEL, Flooded, LifePO4
• Max continuous output current: 100A; max PV input voltage: 100V
• Works with 12V–48V battery banks via automatic voltage detection
• Recommended wiring and startup sequence: battery first, then PV panel

How do I operate, configure, and maintain the unit?

The front LCD and buttons make mode changes and status checks simple: choose among charging modes, light-control, timing or manual control to match your load and schedule. Routine maintenance is minimal — keep ventilation clear, check wire connections, and follow the recommended battery startup sequence for reliable operation.

• Multi-function backlit LCD shows real-time working modes and parameters
• Seven modes including automatic light-control and timing options
• Start-up rule: connect battery first, verify battery voltage, then connect PV panels
• 1-year warranty plus lifetime technical support from ELUSH

Who is this for: The ELUSH 100A MPPT controller is aimed at homeowners, RV and boat owners, tiny-home enthusiasts, and small commercial or agricultural users who need robust battery charging and monitoring for 12V–48V systems. It fits installations that require high current handling, multiple battery chemistries, and a clear visual interface for system diagnostics without specialized tools.
